A manufacturing a container makes it possible to easily manufacture a container including a body portion with a shape that expands outward toward an upper face side. A method for manufacturing a container according to the disclosure is a method for manufacturing a container made of metal, including a bottom portion and a body portion, open on the upper face side, and having a shape in which the body portion expands outward toward the upper face side. The method includes a bottom drawing step of reducing a diameter of a cup body made of metal and having a bottomed cylindrical shape by operating a diameter reducing die having a hole portion with a smaller diameter than an outer diameter of the cup body along a cylindrical axis direction from a bottom side, in which the bottom drawing step is repeated a plurality of times.

Method for manufacturing container and apparatus for manufacturing container

A method for manufacturing a metal bottle having a mouthpiece in an upper part of a bottomed cylindrical bottle body, including forming a screw part on the mouthpiece and then forming a curl at a tip of the mouthpiece. During formation of the screw part, a height of the first-stage screw thread from a tip side in a complete screw part and a height of the second-stage screw thread from the tip side are substantially equal and a distance between an apex part of the first-stage screw thread and a bottle axis is smaller than a distance between the apex part of the second-stage screw thread and the bottle axis. After formation of the curl, a distance between the apex part of the first-stage screw thread and the bottle axis and a distance between the apex part of the second-stage screw thread and the bottle axis are substantially equal.

The present application improves the shape of a curl part of a bottle can to secure high sealability even under high pressure in the can and during heat sterilization, makes bubbling-over occur less during cap opening, and suppresses misrecognition of reseal. A bottle can has a curl part provided at an opening end of a mouth part. The curl part includes an outer wall part extending downward from an upper end bent part. The outer wall part includes a first bent part shaping a locking part that extends continuously and downwardly from the upper end bent part and shapes an outwardly-protruding convex, and a second bent part that extends continuously and downwardly from the first bent part and shapes an inwardly-protruding convex.

A bottle can has a curl part at an opening end of a mouth part thereof. The curl part has an upper end curved part in which an upper part of a neck shoulder part of the mouth part is curved outward and an outer wall part extending downward from the upper end curved part. A predetermined angle at which an outer edge side of a lower end face of the outer wall part opens is formed between the lower end face of the outer wall part and the neck shoulder part. An inner edge of the lower end face comes into contact with the neck shoulder part when a downward load is applied to the curl part from above.

Provided is a conveyance device capable of reducing the speed of conveyed objects, with the interval therebetween being narrowed substantially, while arranging the conveyed objects, which have been carried in one row, in a plurality of rows. The present invention includes a conveyance turret () that holds and conveys conveyed objects (K) and a carrying-out turret () that holds the conveyed objects (K) and transfers the same to a carrying-out conveyor (), wherein the carrying-out conveyor () is configured to hold the conveyed objects (K) in a plurality of rows and carry out the same, the carrying-out turret () is provided in plurality so as to correspond to the plurality of rows of the carrying-out conveyor (), and the conveyance turret () and the carrying-out turret () have an interval adjustment mechanism that changes radial positions of the held conveyed objects (K) according to rotation angles thereof.
